core: Setting max_while_loops to zero now allows infinite loops

- I wanted to be able to have a Kamailio process running a configuration route all the time (sleeping itself using usleep). To do this I use rtimer to create a mode one timer (with timeout of one second - so the route is run very shortly after Kamailio starts). - In the route for this timer I had a while(1) loop, but the max_while_loops (defaulting to 100) meant that the loop wasn't really infinite. - Now setting max_while_loops to zero disables the infinite loop check.
